Also the callers assume that the max number of upper devices is MAX_NEST_DEV and allocate excluded_devices[1+MAX_NEST_DEV] on the stack, but that assumption is not correct and the number of upper devices could be larger than MAX_NEST_DEV (e.g., many macvlans), causing a stack-out-of-bounds write.  Add a max parameter to get_upper_ifindexes() to avoid the issue. When there are too many upper devices, return -EOVERFLOW and abort the redirect.  To reproduce, create more than MAX_NEST_DEV(8) macvlans on a device with an XDP program attached using BPF_F_BROADCAST | BPF_F_EXCLUDE_INGRESS. Then send a packet to the device to trigger the XDP redirect path.",null,[],[],[],[14],{"_key":15},"CVE-2026-23359",[],[],[],"2026-03-25T11:16:34.740Z","2026-06-15T19:06:11.205124329Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24],{"url":25,"sources":26,"tags":28},"https://security-tracker.debian.org/tracker/CVE-2026-23359",[27],"osv_debian",[29],"Advisory",[],[],[33],{"source":27,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":34,"cvss_v4_0":9},{"baseScore":35,"baseSeverity":9,"vectorString":36,"impactScore":37,"exploitabilityScore":38},7.8,"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H",9.8,4.6,[40,61],{"ecosystem":41,"name":42,"vendor":43,"product":42,"cpe_part":9,"purl_type":44,"purl_namespace":43,"purl_name":42,"source":9,"versions":45},"Debian","linux","debian","deb",[46,50,51,55,58],{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},{"version":52,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":53,"version_end_type":54,"fixed_in":9},"lt6_1_170_1","6.1.170-1","excluding",{"version":56,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":57,"version_end_type":54,"fixed_in":9},"lt6_12_85_1","6.12.85-1",{"version":59,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":60,"version_end_type":54,"fixed_in":9},"lt6_19_8_1","6.19.8-1",{"ecosystem":41,"name":62,"vendor":43,"product":62,"cpe_part":9,"purl_type":44,"purl_namespace":43,"purl_name":62,"source":9,"versions":63},"linux-6.1",[64],{"version":65,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":66,"version_end_type":54,"fixed_in":9},"lt6_1_170_1~deb11u1","6.1.170-1~deb11u1"]
